React Util js 文件不能使用绝对路径？

Question

I'm using create-react-app. No eject.

I need help figuring out why this doesn't work.

import { capitalizeFirst } from 'util/util.js'; //This one doesn't work

import AdminInput from 'components/AdminInput/AdminInput.jsx';

console.log(capitalizeFirst); // returns undefined

and my .env

NODE_PATH=src/

and my util.js

export function capitalizeFirst(string) {
    return string.charAt(0).toUpperCase() + string.slice(1);
}

The other components work as expected. Using the function will also result in "TypeError: _util.capitalizeFirst is not a function" or something like that.

However, if I use

import { capitalizeFirst } from '../../util/util.js';

it will print the correct function instead.

I don't understand why the js file doesn't work but the React Components work with an absolute path?

它从node_modules解析为util/util
